in chicory hairy root cultures, transcription factor CiMYB5 displays co-expression with its target genes in response to different abiotic stress and phytohormone treatments, whereas correlations with CiMYB3 expression are less consistent. Oligofructan levels indicate that the metabolic response, while depending on the balance of the relative expression levels of fructan exohydrolases and fructosyltransferases, can be also affected by differential subcellular localization of different FEH isoforms. In chicory hairy root cultures CiMYB5 and CiMYB3 act as positive regulators of the fructan degradation pathway |

regulation of the expression of FEH genes is a crucial factor for overwintering ability of fructan-accumulating cereals and grasses. The coordinated expression of FEH genes in wheat is related to the regulation of water-soluble carbohydrate accumulation from autumn to early winter and fructan consumption under snow cover as well as energy supply. Wheat FEHs also play an important role in the varietal difference in freezing tolerance and snow mold resistance. Cooperative expression of 6-FEH and 1-FEH genes might be related to the seasonal changes and varietal difference in mono- and disaccharide contents |

| 3.2.1.153 | metabolism |
snow molds consume carbon sources contained in the inoculated wheat tissues but cannot effectively use wheat polysaccharide including fructans compared with mono- and disaccharides. Therefore, in snow mold inoculated wheat tissues, fructans are rapidly degraded, mainly by wheat enzymes, FEHs, to maintain necessary levels of mono- and disaccharides for metabolic demands under snow cover |

| 3.2.1.153 | physiological function |
1-FEH activities are higher in all DH 338 stem segments under drought, as compared to irrigated plants after 10 days after anthesis (DAA), although in the sheath the difference disappears during the later stages. Under drought, 1-FEH activity tends to increase in the peduncle and the penultimate internode after 14 DAA, while it remains similar between treatments in the lower parts and sheath in DH 307. The combined 1-FEH and 6-FEH activities are particularly important during the later stages in drought treated DH 338. FEH dynamics under drought may play a more essential role in var. DH 307 than in var. DH 338 |

fructan 1-exohydrolase enzymes are involved in inulin degradation in the roots of chicory. Higher enzyme expression in cold temperatures can decrease the quality and the quantity of the inulin |

fructan exohydrolase, FEH, gene plays a key role in fructan metabolism associated with wintering ability, especially for snow mold resistance. Gene 1-FEH w1 is thought to code a trimming enzyme |
